Patient Satisfaction in Occlusal Splints Fabricated Using Fully Digital Versus Conventional Workflow

The traditional workflow of occlusal splints includes, primary impression for both arches, pouring casts, patient deprogramming and centric jaw relation record followed by mounting. Then the occlusal splint is made out of a resin that includes wax pattern fabrication on surveyed and mounted casts to be invested finally to form a clear, heated-cured acrylic resin splint. After that, it is trimmed, polished, and seated back on the duplicate of the invested casts. It is a complicated process and time- consuming constructed followed by occlusal adjustments on the articulator. That traditional approach is time consuming and prone to many technical errors. Such errors are reflected in occlusal discrepancies that are considered critical for the effectiveness of occlusal splint therapy. Recent advancements in the field of intra-oral scanning (IOS), jaw tracking device for digitally recording the maxillomandibular relationship, maximum intercuspation, centric occlusion and the patient's mandibular motion. This technique incorporates the mandibular motion into the 3-dimensional (3D) virtual patient representation to integrate the 3D dynamic virtual patient visualization and computer-aided design/computer-aided manufacturing (CAD/CAM) may have the potential to compensate for some of the shortcomings of conventional splint therapy and deliver improved clinical results, while simplifying the workflow. Several studies have shown the improved quality and material properties of CAD/CAM splints in comparison to conventional ones, but little of them reported fully digital workflow starting from scanning of maxillary and mandibular teeth, using jaw tracking device to obtain personalized condylar motion parameters and individualized maxillary position to better simulate the actual movement of the patient in the laboratory (Revilla, Marta etal,2022) and Computer-aided design/computer-aided manufacturing (CAD/CAM) in final production of occlusal splints all of these fully digital steps may be possibly reducing the adjustment time for occlusal devices and achieving predictable efficacy. This study aims to compare the difference, if present in patient satisfaction and the amount of occlusal adjustments in occlusal splints fabricated using fully digital versus conventional workflow.
